Affliction.

[Lawrence]

The light in me cannot be seen through yarn-worked lace.
It has no frills, it never flickers, it creates no shadow boxers(Great opening!)
on white stucco walls. No mesmeric dancers shimmer (On white stucco walls seems clumsy to me)
with that dark sultry hip shaking shimmy. ( is "sultry" needed?)

My light is borne of black tallow from dead dreams (Dead dreams seems a bit cliche)
and a wick of willow bark, it burns green and dark. (Great image! My favorite line so far.)
It depresses the candour of daylight (Seems a little fluffy and weak)
decries the sound of angel song from ebullient choristers (Solid)
and defeats all vestige of that trifle called life (I'd X defeats. Doesn't seem like it's needed)

The light in me cannot be shared or given like a gift (Like a gift seems a bit cliche)
It has a gravity that pulls in prey. Its incandescence (Awesome line)
heated with each new days conquest of the failed.(Solid)
It feeds at the trough of one’s despair. (I like it!)

Great work! Why do a get the vibe that this contains a little bit of an ode to the sadist?
Well done!
